"Star Wars: The Force Awakens."

With Rey in "The Force Awakens," "Star Wars" added another
strong female hero to its universe.

But a dark theory suggests Rey might not be a hero at all.

Instead, she could be the franchise's newest villain.

The
question of Rey's parentage was one of the biggest mysteries
surrounding the newest "Star Wars" and could help explain her
natural ability to use the Force with so little training, while
Luke Skywalker had to endure Yoda's trials in the original
trilogy.

But all we can do is assume Rey is Luke's daughter for now and
wait until later episodes fill us in.

In the meantime, this theory compiled by
Uproxx uses the information given in "The Force Awakens"
film and novelization. The film shows how easy it is for Rey to
use the Force and the novelization, which is canon, says during
her and Kylo Ren's climactic battle that she heard a voice from
the dark side that told her to kill Kylo Ren.

And like Anakin Skywalker aka Darth Vader, Rey suffered a very
troubled childhood and is full of anger and fear over the death
of her father figure Han Solo.

Most convincing of all, the video explainer points out how in the
"Force Awakens" poster, Rey's staff lines up perfectly with Kylo
Ren's red lightsaber — the kind members of the Sith use —
meaning Rey is literally positioned to take over using the Sith's
weapon and therefore become a member of the dark side.
